Here are several bugfixes and updates of perf-probe andkprobe-tracer.This updates includes --line option support which you arewaiting for :-).

For kprobe-tracer, I decided to drop $argN support, becausethe ABI for each function strongly depends on not only thearchitecture but also the API of the function and gcc options.Anyway, we already have perf-probe which allows us to findregister/memory assignment of each arguments.
